US5695726A - Removal of mercury and cadmium and their

Toxic metal vapor phase compounds, and in particular, mercury and cadmium, are removed from waste incinerator combustion gases by contact with dry alkaline material and dry activated carbon followed by solids separation. The resulting gas is subjected to quench/wet scrubbing with recycle hydrochloric acid solution formed in situ by absorption of HCl from the gas.

Dealing with mercury in an old heating system

Feb 23, 2016 · The Heat Generator was a simple device with just one moving part, that being the pint or so of mercury. You can see it on the steps here in front of his shop. Mark H. used a pipe within a pipe that dipped into the mercury pot to separate the system water from …

the catalytic process to preheat the waste gas. The heart of an incinerator system is a combustion chamber in which the waste stream is burned. Since the inlet waste gas stream temperature is generally much lower than that required for combustion, energy must be supplied to the incinerator to raise the waste gas temperature.

(PDF) Mercury transformation and speciation in flue gases

The waste heat boiler recovers heat from the flue gas by converting water pumped through hundreds of metal tubes into steam. 8 Powdered activated carbon is injected into the flue gas to remove mercury.

Oct 06, 1995 · The incineration waste gases are preferably cooled in a heat exchanger or other means to cool the gases, such as a waste heat boiler, to a temperature in the range of from about 150° C. to about 290° C., preferably from about 175° C. to about 235° C. In waste heat boiler 8, boiler water feed is converted to steam in line 9.
